This has been upped before, but, has not been seeded in a long time.  This was recorded in 2004 - as the title says, Chicago and Earth Wind & Fire Live at the Greek Theatre.  If you like horn bands, in my opinion, this is the ultimate concert.  It's a good time to sit back and enjoy some music.  I am using a VPN so seeding will not be super fast.  The format is .M4V, which is .MP4 by another name - change the extension if your video player of choice has an issue (can't imagine there would be a problem). Peace to all
